Dennis,
Its nice that you forged a friendship with your Nurse in the hospital, sometimes we want to help people from the Philippines, but the reality is, you can do little to alleviate your Nurse's situation.
This type of relationship break up is quite common in the Philippines, but as she is a Philippine citizen and subject to the family code, she may not constitute a divorce in the UK, as it would not be recognized under Philippine law.
Whilst she may have permanent residency status, she is still a Filipino, and would have to consult a Filipino family law practice to take her case further, and I doubt whether she would ever get an anulment based on her husband deserting her, the most she may get is a legal separation.
She could wait until such times as she can apply to be naturalized as a British citizen, then she may apply here in the UK to divorce the husband for desertion, but that would take about 5 years before a court would grant the decree, its a long road she has to travel...
And my advice to you is for you not to get on that road with her, by sympathetic, listen to her woes and concerns, but do not offer to help, because quite frankly, you cannot.
Best of luck.
